Firmware unresponsive

[blowback]

Hi!

I flashed a svlinky 0.2 with a config from here https://github.com/arduxio/zmk-ardux.git editing its config/west.yml to:

manifest:
  remotes:
    - name: zmkfirmware
      url-base: https://github.com/zmkfirmware
    - name: zmk-ardux
      url-base: https://github.com/arduxio
    - name: sadekbaroudi
      url-base: https://github.com/sadekbaroudi
  projects:
    - name: zmk
      remote: zmkfirmware
      revision: 8c6bda260ace119b3c22a21bdcdd6d17a83fc5eb
      import: app/west.yml
    - name: zmk-fingerpunch-controllers
      remote: sadekbaroudi
      revision: main
      import: config/deps.yml
  self:
    path: config

I'm building a "Paintbrush" 8 key keyboard, and this is, I think, an older config intended for Arduino pro micro controllers so I changed the_paintbrush_left.overlay to:

    status = "okay";

    oled: ssd1306@3c {
        compatible = "solomon,ssd1306fb";
        reg = <0x3c>;
        label = "DISPLAY";

    };

    kscan0: kscan_0 {
        compatible = "zmk,kscan-gpio-direct";

        label = "KSCAN";

        input-gpios
            = <&pro_micro 18 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 19 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 20 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 21 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 10 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 16 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 14 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            , <&pro_micro 15 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>
            ;
    };
};

The difference is basically mapping the 8 keys to different GPIOs, to match those in your sparkfun_pro_micro.dtsi:

I then build this with:

west build -p -b svlinky@0.2 -- -DSHIELD=the_paintbrush_left -DZMK_CONFIG=$D/zmk-ardux/config

which successfully produces a zmk.uf2 board. If I drag this on to the RPi mount the device reboots, and then is dead - does not USB enumerate. I have to short the boot pins and reset->gnd to recover the device.

I tried adding debug:

west build -p -b svlinky@0.2 -- -DSHIELD=the_paintbrush_left -DZMK_CONFIG=$D/zmk-ardux/config -Szmk-usb-logging

but the behaviour was the same.

Is there anything else I can try to diagnose the issue? Is there a known-good svlinky firmware that might work (in part) with my 8 key keyboard?

I should add that my first attempt was with the controller in the board, second attempt was with the controller isolated (the board buzzes out ok, but you never know...).

@blowback - take a look at this thread. I think you're running into the same issue. I'll update the documentation to be clearer about doing local builds https://github.com/sadekbaroudi/zmk-fingerpunch-controllers/issues/1

[blowback]

Haha you're right: that is me also! I've managed to resolve the build issues, now I'm getting a runtime crash. Can I attach an ftdi to those tx and rx pins and get some console output? what are the serial settings?
